Natural flavonoid Orientin restricts 5-Fluorouracil induced cancer stem cells mediated angiogenesis by regulating HIF1α and VEGFA in colorectal cancer.
Article in Molecular medicine (Cambridge, Mass.), 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 5 papers, 1 of them a synthesis that pooled it.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
backgroundCancer stem cells are a small subpopulation of cells which are responsible for tumor metastasis, angiogenesis, drug resistance etc. 5-Fluorouracil (5FU), a common therapeutic drug used in colorectal cancer treatment is reported to enrich CSCs, tumor recurrence and induces severe organ toxicities resulting in poor clinical outcome in patients. Therefore, we introduced a natural flavonoid Orientin in combination with 5FU to mitigate the CSC mediated angiogenesis and induced toxicities.
methodsTumorosphere generation, flow cytometry, immunofluorescence assay, and western blotting were performed by using 5FU and Orientin individually and both treated colorectal cells and CSCs. In silico study was carried out to check the interaction between HIF1α and Orientin. In ovo chorioallantoic membrane (CAM) assay and tube formation assay using HUVECs were performed to monitor CSC mediated angiogenesis. In vivo CT26 syngeneic mice model was used to validate in silico and ex vivo results.
resultsWe found that 5FU treatment significantly increased the CD44
conclusionsThis novel treatment strategy of "Orientin with 5FU" is likely to improve the efficiency of conventional chemotherapy and may suppress disease recurrence in colorectal cancer by limiting CSC mediated angiogenesis.
